M4 x 30mm 錐點內六角止付螺絲 | 合金鋼 (250 顆/包)

Had to tighten a few cam locks on a jig and these M4s grabbed perfectly without stripping. The hex socket drive made it easy to reach into a cramped space.

The cone point bites into the shaft nicely before the hex key even feels tight. Used a full pack on a jig build and not a single one stripped under load.

These arrived well-packaged and the hex socket drive made tightening them in a cramped spot much less frustrating than I anticipated. The cone point seats firmly, so I'm confident they'll hold up under the vibration my application throws at them.
